Start - Read/Write
The STRT value is the value of the Horizontal down
counter at which the HACTIVE signal becomes active
(starts). This indicates the start of the active video portion
for the Horizontal line. Please refer to video signalling
timing diagrams in
is an internal block signal. The active video interval is
controlled by the logical OR of VACTIVE and HACTIVE.
Reserved - Unknown during read
Stop - Read/Write
The STOP value is the value of the Horizontal down
counter at which the HBLANK signal becomes inactive
(stops). This is used to generate the BLANKn signal that is
used by external devices to indicate the end of the active
video portion for the Horizontal line. Please refer to video
signalling timing diagrams in
HBLANK is an internal clock signal. The BLANKn output is
a logical AND of VBLANK and HBLANK.
